In order to promote green urban renewal and build sustainable green and low-carbon residential communities,this paper is a scientific assessment of the green and low-carbon levels of communities based on the theory of the sciences of human settlements.Firstly,an evaluation framework for community green and low-carbon level is constructed and a system of evaluation index is established from the perspective of livability of residents.By using the subjective-objective combined weighting method of AHP and CRITIC,the comprehensive weights of the evaluation indicators are calculated and a community green low-carbon level assessment model is developed based on matter-element extension.Finally,this assessment model is applied to typical green low-carbon communities in each district of Qingdao.The results show that the green low-carbon levels of the community vary in different dis-tricts of Qingdao.In the selected communities,the green low-carbon levels of Community B in Shinan District,Community H in Huangdao District and Community S in Laoshan District are relative high,which are all at an excellent level,while the green low-carbon levels of Community N in Shibei District and Community C in Licang District are good and medium,respectively,which are positively correlated with the level of local economic development in different administrative districts.Furthermore,corresponding countermeasures and suggestions are put forward for communities with different green and low-carbon levels.
